Our back garden slopes downhill to meet the house 4' above the internal ground level, we intend to dig down the 4 feet and install a french drain to a soakaway.
I know I have seen a product with which we can line the external face of the wall where the wall side is corrugated to allow airflow next to the wall and the outside face is a strong flat surface to hold back the water/backfill.
The thing is, since researching it i can no longer find the product which looked ideal!
There are lots of similar products which work in conjunction with dpm coating s for the wall but I'm worried that these won't allow the wall to breath.
Any help greatly appreciated.
